Despite all that has happened, Caroline is determined to see that Elena, Bonnie, Matt and Tyler all enjoy a traditional Senior Prank Night before the school year begins at Mystic Falls High School. However, when uninvited guests show up, it doesn't take long for the evening to take a deadly turn. Damon convinces Jeremy that he can use his new connection to the other side to help find a way to defeat Klaus. Finally, Klaus deepens his hold on Stefan and uses him for increasingly violent and dangerous purposes.

As the high school prepares to throw a "1960s Decade Dance," Elena starts receiving disturbing messages from Klaus via an unusual source. Bonnie tries to reassure Jeremy that she is strong enough to help Elena, but a worried Jeremy asks Stefan for advice. Caroline talks Matt into taking her to the dance. Expecting Klaus to show up at the dance, Damon and Alaric attend as chaperones, but Klaus is playing a complicated game that keeps them on edge. Finally, Damon comes up with a new plan of action that shocks and upsets everyone.
